CAR-HEATER.

Be it known that I, EDWARD P. Conn, a citizenof the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Car-Heaters; of which the following is a specification.

My present invention relates particularly to -car heaters r and is designed to provide a stove adapted to use either charcoal or a prepared briquet fuel, which requires no smoke pipe and which is adapted to give a uniform temperature over a period of at least two or three days without attention, and at the same time be fireproof itself and capable of use without, the emission of sparks even to the upsetting of the stove itself or the upsettin or wrecking of the car in which itis used.

In the accompanying drawings which illustrate my invention,

Figure 1 is a side elevation illustrating the complete stove set up in operative position.

Fig. 2 is a top plan view thereof.

Fig. 3 is a central vertical section taken therethrough. I

Fig. 4 is a horizontal section taken substantially on line H of Fig. 3.

' Fig. 5 is a similar view taken substantially on line 55 of Fig. 3.

Fig. 6 is another similar view taken substantially on line 66 of Fig. 3. Fig. 7 is a detailperspective view illustrating certain of the relatively engaging connecting members of the upper and lower stove sections, and i V Fig. 8 is a detail vertical section through the ash pit door and its locking device and taken substantially on line 88 of Fig. 1.

Referring now to these figures it will be generally seen that I provide a car heater in the form of an upright cylinder, the wall of which is constructed for the most part of corrugated metal. This stove is in two sections of which theupper section A is the magazine and has a rolled edge a surrounding its-lower open end and a top a having a central opening and a depending inclined flange a around the said opening. By reference particularly to Figs. 1, 2 and 3 it will be seen that a central lid B generally circular in form is provided with'an-gular flanges 1) extending therearound to fit within the opening of the top a and against the flange a thereof to normally close the feed Specification of Letters Patent.

opening in the top of the magazine thus constructed, the said top at having cleats along with the handle B whereby the lid may be raised, lowered and turned. This lid is connected by a chain 6 or other flexible fastening means to the magazine top .a' in order to prevent its loss.

The wall of the magazine section A is also provided adjacent its top with exterior straps a which serve as connections for the upper ends of anchoring chains C, the opposite ends of these chainsbeing provided wit snap hooks 0 for engagement with floor eyes C and the like, as best seen in Fig. 1. to

prevent the stove from turning over in transit.

Adjacent its lower end themagazine sec: tion A is provided with an internal hopper D, this hopper having a central opening and being generally in the form of an inverted frustum of a cone, and provided with ac'ircular vertical wall Ddepending around its opening 03 and having a lower curled edge d.

Slidably adjustable upon the upper inclined surface of the hopper D, 1s a 6 ntrolling plate E, the outer end of which projects through a slot A in the wall of the section A and is curled to form. a handle e by which the plate may be moved inwardly and outwardly. In its inner position as shown clearly in Figs. 3 and 4, the controlling .plate E has its enlarged inner end disposed within the circular depending wall D in such manner as to cut off feed from the magazine section A through its hopper opening (I. The adjusting plate E-also has one or more apertures e which in the "adjusted position of the plate to permit limited feed, may extend beyond the wall of the magazine section in order to receive a looking pin 0 which is connected by a chain or flexible member 0 to the wall of the magazine section to prevent its loss. In this manner the slide may be prevented from accidental movement when in outwardlyadjusted position, which might otherwise result in cutting off the feed when such action is not desired.

' The rolled edge a of the magazine section A rests upon the rolled edge 7? surrounding the upper open end of the fire box section F and these contacting edges of said sections are provided with relatively. enga in lugs G, the flanges G'.o'f which are adapted to lap one another and to be brought into operative engagement bya relative rotary movement of the unner or magazine section A with respect to the lower or fire box section F as bestseen byreference to Figs. 1 and 7 the said flanges G having a recess 9 at their inner edge adapted to aline with one another in theconnected position of the parts whereby to receive locking pins and the like in the form-for instance'of the snap hook Gr as seen in Fi, 1, which is preferably connected by a exible connection in the form of a chain G to the upper sectio A to prevent loss thereof.

The magazine section A also rests, by

means of small brackets D secured to the 'lower surface of its hopper D, upon the top H of the removable cylindrical fire pot-H, the circular wall of which is provided with a lower rolled edge It. and with an inner lining strip h whereby to support an intermediate layer 72 of asbestos and the like. The said top H has a central opening through which the circular wall D depends V as clearly shown in Fig. 8 and the base of the removable fire pot H is reticulated, being formed of a heavy wire mesh as indicated at H and best seen in Figs. 3 and 5.

Tlie lower rolled edge h of the fire pot H,

as best seen in. Fig; 3, rests upon the inner flanged portion .of a stationary draft ring I secured around the interior of thefire box section F at an intermediate point and 7 in substantially the shape, of a trough where- I by to support therein a movabledraft ring 1', best seen in Figs. 3 and 5. This movable draft ring is provided with a handle I extending outwardlythrough a slot in the wall of the fire box section F, as best seen in Figsl and 5, the said wall slot being horizontalwhereby the ring I may be permitted a limited Circular movement. A bracket I is secured exteriorly of the fire box section,

as best seen in the figures last-mentioned,-

and is provided with a plurality-of apertures 21 into registry with each of which an aperture i of the handle I may be brought whereby to receive a locking pin 1* for the I strap or bracket 'M secured to the exterior and the base J of the ash pit is provided with spaced guides y" upon its upper surface to provide for the engagement of the. base plate K of an oil lighter K elevated above the said base plate upon legs is and having a gauze covering W, the base plate K having 'a handle 72 whereby it may be readily disposed within and removed'from engaging structure of the ash pit and the. lighter preventing accidental loss of the latter when the ashes are removed. a

' The door opening J 2 is normally covered by a door L vertically slidable exteriorly of the fire box'seotion F in guides L and this door is provided with a longitudinally slotted locka ing member the slot of which is disposed on a pivot bolt U of the door so as to per- 0 mit the said locking member to move freely and swing between lugs Z. The lower end of the locking member M has a spear-shaped extremity m engageable with one side of a of the fire box 'section below the door L whereby to thus form an automatic locking device which will hold the. fire box door L in lower closed position in case it drops down in-the guides L for any reasonsuch'as-tlie overturning of the stove or sudden excessive jarring of the car. in which the stove is erected, as incase of wreck.

Below the ash pit J the fire box section F is provided with a ventilated-base divided by ahorizontal transverse plate N into upper and lower chambers N and N the said plate N having a lowerlayer of asbestos n and openings n. The Wall of the fire box sectionF is also provided with annular series of openings n and n 'respectively above and below the plate N so that this ventilated base, with the double wall base J of the fire pot itself, effectively prevents the comfnunica- T15 tion of-excessive' heat to the floor of the car upon which thest'ove is secured. The lower angular ends of uprights O'secured within the ventilated base of the stove section F, are provided with apertures o for the reception of nails, screws or other fastening members whereby the said stove section may be securely fastened to the floor of the car within which it is used and thus with the chains C1 securely fastened as shown in Fig. 1, the entire stove is effectively prevented from overturning.

Air enters the fire box section F through an annular series of small apertures f below the draft ring I, and the movable ring I being properlyadj ust'ed, more or less of this air the guides j. in the ash .pit, this relatively A below the hopper D.

' the space, findin is permitted to pass up through the openings '5 and the remainder passes up through the fire pot H. The draft of the fire pot is thus efl'ectively controlled.

Air to be heated also passes into the space around the fire pot wall through an annular series of openings f in the lower section above the draft ring I and circles around its way out through an annular series 0 openings a in the lower. portion of the wall of the magazine section Thus with the part in position, as shown in Fig. 3, all danger of the emission of sparks from the stove is guarded against, andin addition, the particular construction, as before described, prevents overturning of the stove except in case the car in which it is used is wrecked or overturned, and even in this case the emission of hot coals or sparks is guarded against. Even with the ash pit door in elevated position to permit maximum draft, any sudden jolt or jar suflicient to ermit the same to descend in its guides, Wlll cause automatic engagement of the member M and will result in locking the said door in lower closed position.

It will be noted that by removing the magazine section A, the fire pot H may be readily withdrawn as a whole, carrying the .reticulated base H, which forms a grate,

therewith, and by this means ready access may be had to all parts of the ash pit J for any purpose whatsoever.
